| Research Abstract |
The mechanism of laser ablation and its application to the formation of functional inorganic materials have been studied in this international joint research program. In the first year (1994 fiscal year), the ablation mechanism was studied by using excimer laser and mas-spectroscopy. It has been revealed that the emitted atoms and molecules are formed photochemically through multi-photon processes. The effect of the energy of particles on the thin film formation was established. In the second year (1995 fiscal year), formation of ferroelectric and superconducting artificial lattices were studied. It has revealed that strained superlattice which shows large dielictric constant can be constructed by this particular laser ablation. New superconductors with the control of the number of CuO_2 plane have been also formed using the laser ablation technique.
